Warnings and Cautions
This Section provides warnings and cautions pertinent to this product, that if not
heeded, may result in personal injury, fatality, or equipment damage. Yaskawa is
not responsible for consequences of ignoring these instructions.
YASKAWA manufactures component parts that can be used in a wide variety of industrial applications. The selection and
application of YASKAWA products remain the responsibility of the equipment designer or end user. YASKAWA accepts no
responsibility for the way its products are incorporated into the final system design. Under no circumstances should any
YASKAWA product be incorporated into any product or design as the exclusive or sole safety control. Without exception, all
controls should be designed to detect faults dynamically and fail safely under all circumstances. All products designed to
incorporate a component part manufactured by YASKAWA must be supplied to the end user with appropriate warnings and
instructions as to that part’s safe use and operation. Any warnings provided by YASKAWA must be promptly provided to the
end user. YASKAWA offers an express warranty only as to the quality of its products in conforming to standards and
specifications published in the YASKAWA manual. NO OTHER WARRANTY, EXPRESS OR IMPLIED, IS OFFERED.
YASKAWA assumes no liability for any personal injury, property damage, losses, or claims arising from misapplication of its
products.
•Read and understand this manual before installing, operating, or servicing this Drive. All warnings, cautions, and
instructions must be followed. All activity must be performed by qualified personnel. The Drive must be installed according
to this manual and local codes.
•Do not connect or disconnect wiring while the power is on. Do not remove covers or touch circuit boards while the power is
on. Do not remove or insert the digital operator while power is on.
•Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply
is turned off. Status indicator LEDs and Digital Operator display will be extinguished when the DC bus voltage is below
50 VDC. To prevent electric shock, wait at least five minutes after all indicators are OFF and measure DC bus voltage level
to confirm safe level.
•Do not perform a withstand voltage test on any part of the unit. This equipment uses sensitive devices and may be damaged
by high voltage.
WARNING
WARNING

ii
•The Drive is not suitable for circuits capable of delivering more than the specified RMS symmetrical amperes. Install
adequate branch short circuit protection per applicable codes. Refer to the specification. Failure to do so may result in
equipment damage and/or personal injury.
•Do not connect unapproved LC or RC interference suppression filters, capacitors, or overvoltage protection devices to the
output of the Drive. These devices may generate peak currents that exceed Drive specifications.
•To avoid unnecessary fault displays caused by contactors or output switches placed between Drive and motor, auxiliary
contacts must be properly integrated into the control logic circuit.
•YASKAWA is not responsible for any modification of the product made by the user; doing so will void the warranty. This
product must not be modified.
•Verify that the rated voltage of the Drive matches the voltage of the incoming power supply before applying power.
•To meet CE directives, proper line filters and proper installation are required.
•Some drawings in this manual may be shown with protective covers or shields removed, to describe details. These must be
replaced before operation.
•Observe electrostatic discharge procedures when handling circuit cards to prevent ESD damage.
•The equipment may start unexpectedly upon application of power. Clear all personnel from the drive, motor, and machine
area before applying power. Secure covers, couplings, shaft keys, and machine loads before energizing the Drive.
•Please do not connect or operate any equipment with visible damage or missing parts. The operating company is responsible
for any injuries or equipment damage resulting from failure to heed the warnings in this manual.
Intended Use
Drives are intended for installation in electrical systems or machinery.
For use in the European Union, their installation in machinery and systems must conform to the following product standards of
the Low Voltage Directive:
EN 50178, 1997-10, Equipping of Power Systems with Electronic Devices
EN 60201-1, 1997-12 Machine Safety and Equipping with Electrical Devices
Part 1: General Requirements (IEC 60204-1:1997)/
EN 61010, 1997-11Safety Requirements for Information Technology Equipment
(IEC 950:1991 + A1:1992 + A2:1993 + A3:1995 + A4:1996, modified)
CE certification is carried out to EN 50178, using the line filters specified in this manual and following the appropriate
installation instructions.
Other
The E7 Drive is suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical amperes, 240Vac
maximum (240V Class) and 480Vac maximum (480V Class). When protected by a circuit breaker or fuses having an
interrupting rating not less than 100,000 RMS symmetrical amperes, 600Vac maximum.

Introduction
This Section describes the applicability of this User Manual
The E7 Drive is a Pulse Width Modulated Drive for AC induction motors. This type of Drive is also known as an Adjustable
Frequency Drive, Variable Frequency Drive, AC Drive, AFD, ASD, VFD, and Inverter. In this manual, the E7 Drive will be
referred to as the “Drive”.
The E7 Drive is a variable torque AC drive, designed specifically for HVAC applications in building automation, including
fans, blowers and pumps. A new benchmark for size, cost, performance, benefits, and quality, the E7 includes numerous
built-in features such as network communications, H/O/A, PI, and energy-savings functions.
The E7 has embedded communications for the popular building automation protocols, Johnson Controls Metasys®and
Siemens APOGEETM FLN, as well as Modbus®. An optional LONWORKS®interface card is also available.
The LCD keypad/operator is equipped with Hand/Off/Auto functions, copy feature, 7 language choices, and 5 lines of display
with 16 characters per line. Optional software allows upload/download, as well as graphing and monitoring of drive
parameters from a PC for ease of drive management. User parameter settings can be recovered at any time via “user initializa-
tion”.
Built-in PI eliminates the need for closed loop output signals from a building automation system. It includes feedback display,
inverse, square root and differential control functions, and maintains setpoint for closed loop control of fans and pumps for
pressure, flow, or temperature regulation.
This manual is applicable to E7 Drives defined by model numbers of CIMR-E7U_ _ _ _ . These models are designed for sale
and use in North and South America.
This manual is subject to change as product improvements occur. The latest version of the manual can be obtained from the
Yaskawa website www.drives.com . The date shown on the rear cover is changed when revisions are made. The latest version
of Drive software is also shown.
In this manual, some figures portray the product with covers removed for clarity. The Drive should never be operated without
covers installed.
